Fabrication of cryostable, low-loss cable for a 3. 8 MJ pulsed superconducting coil
For large pulsed coils such as the ohmic heating coils, great reliability as well as low ac losses is essentially required. Therefore, the cryostability must be achieved not only within the first-level cable but within the final cable. To guarantee cryostability within the final cable, a great deal of stabilizing copper will be required, leading to the considerable decrease of the overall current density. To solve this problem, high-purity aluminum is adopted for stabilizer. To reduce ac losses as much as possible, the mixed matrix is used within the filament bundle of the basic strand and the outer sheath is completely composed of CuNi. In the paper, the details of the cable fabrication, the recovery current and ac loss measurements, and the discussions on the stabilities and coupling current losses are presented.
